npc_sniper
is a point entity available in Half-Life 2,
Half-Life 2: Episode One,
Half-Life 2: Episode Two,
Half-Life 2: Deathmatch, and
Black Mesa.
In Half-Life 2 games, this is a Combine soldier with an overwatch sniper rifle which uses blue laser sight, making it capable of extreme accuracy at extreme range.
In Black Mesa, this is a HECU marine with a sniper rifle which uses red laser sight.
The npc_sniper does not actually have its own model - rather, it uses a Combine soldier (or HECU marine in Black Mesa) model in-game (if its Hidden flag is not set) playing its idle animation, with the rifle's laser coming from the center of the hull. Only explosions and burning damage can hurt the sniper.
The sniper doesn't turn on his sight until after he sees the player or an NPC within an acceptable range and angle, and will turn it off again after he is done. He will prioritize the player over any other target. If he loses track of the player, he will get frustrated and shoot three rounds at the area where the player was last seen, often targeting smaller prop_physics (like soda cans, melons, melon chunks, cinderblocks, ...) but not large prop_physics (like soda machines). He will then resume to targeting any other visible targets.
